About this episode
"The statistic you always kind of want to keep in the back of your brain is that over a lifetime, one in eight women will be diagnosed with breast cancer. So that means for an individual assigned female at birth, there's a 13% chance that if that individual lives to age 85, that they will be diagnosed with breast cancer. So, it's the most common cancer diagnosed in this group," Suzanne Mahon, DNS, RN, AOCN®, AGN-BC, FAAN, professor emeritus at Saint Louis University in St. Louis, MO, told Jaime Weimer, MSN, RN, AGCNS-BS, AOCNS®, manager of oncology nursing practice at ONS, during a conversation about breast cancer screening.

Highlights From This Episode "Unfortunately, probably about 42,500 women die every year from breast cancer, and that number still seems really high because mammography screening has really enabled us to detect breast cancer in many, many cases when it would be most treatable. And so that's a place where you would like to see some real progress." TS 3:32 "Primary prevention for all individuals, which is always best to prevent, would include 150 minutes of intentional exercise, watching the diet, keeping that weight as low as possible—we want more muscle and less fat mass—and limiting alcohol intake. Then we go and we talk about screening." TS 7:29 "The most recent statistic, and this kind of is post-COVID, is that 67% of women age 40 and over have had breast cancer screening in the last two years, which means that there's a hunk of women, 33% of women who have not had breast cancer screening in the last two years and that who are 40 and over. And that to me is a really, really sad statistic because that's a missed opportunity for screening." TS 11:32 "Sometimes we forget that women and individuals who've had breast cancer, especially if they had it at a younger age, their risk of a second breast cancer over time is about 1% or 2% per year. So, if you have a first breast cancer at 40, and you live another 30 years, two times 30 is 60, that risk is substantial. A lot of times we don't see as much anymore, which is good. Individuals who had a lot of radiation to the chest, we used to see a lot of young individuals having radiation therapy for Hodgkin's disease that encompassed the chest, and a lot of them were diagnosed with breast cancer afterwards." TS 15:31 "One of the things that always makes me really sad is that probably less than 40% of people who are eligible for this cascade testing, and mind you, many of the laboratories, if we test a parent and say they have a pathogenic variant, they will offer free testing to relatives for 90–120 days in that lab. They don't even have to pay for the genetic test. They just have to get the counseling and send it. But less than 40% of individuals who would benefit from cascade testing ever get it done." TS 35:02 "I have had this privilege of sitting for decades watching genetics. That's the only area I've ever worked in that is always completely changing. And just when you think you got it, there is something new and it's really driving our oncology care. And I would really encourage people, I know we've said it about 10 times now, to look at that Genomics and Precision Medicine Learning Library, there are resources in there if you want to spend 3 minutes, 5 minutes, 10 minutes—if you got a whole hour or two, there's courses. There are so many things in there, and if you really want to become more savvy, you can, and that's a great place to start." TS 45:34
